When I view your website on mobile, it looks okay. I cannot see any problems with the responsiveness on various devices and screen widths.
You should remove the “html” and “head” elements from the custom HTML that you have added on the page, as they are not needed and they also result in incorrect HTML markup.
This is the code you currently have:
<html>
<head>
<link href='https://fonts.googleapis.com/css?family=Rock Salt' rel='stylesheet'>
<p style="font-family:'Rock Salt';font-size:49px;color:#F8B509;text-align:center;">Explore Your Truth</p>
</html>
<p class="has-text-align-center has-text-color has-medium-font-size" style="color:#000000"><strong><span style="color:#898885" class="has-inline-color">Life Coaching and Energy Guidance</span></strong></p>This is how you should write the custom HTML instead:
<link href='https://fonts.googleapis.com/css?family=Rock Salt' rel='stylesheet'>
<p style="font-family:'Rock Salt';font-size:49px;color:#F8B509;text-align:center;">Explore Your Truth</p>
<p class="has-text-align-center has-text-color has-medium-font-size" style="color:#000000"><strong><span style="color:#898885" class="has-inline-color">Life Coaching and Energy Guidance</span></strong></p>
